Abstract

Abstract: Aiming at the disadvantages of low efficiency and incomplete expression in the collection of heteromorphic buildings' features by conventional surveying and mapping methods,this paper takes a tall and heteromorphic building in Nantong as an example. The 3D laser scanner is used as the data acquisition equipment to detect the construction axis by setting control points, collecting point clouds outside of the door and processing the data inside of the door. The accuracy is evaluated.As a result, the feasibility of 3D laser scanning technology in detecting the construction axis of heteromorphic buildings is verified.

Key words: heteromorphic building, construction axis detection, 3D laser scanning technology, point cloud
